AN XPS STUDY OF NITROGEN-SULFUR COMPOUNDS

An X-ray photoelectron spectroscopy study has been conducted on a seri es of nitrogen-sulfur compounds to characterize the charge shifts on t he nitrogen and sulfur atoms in the molecules. In all of the compounds , the sulfur was found to have a Is binding energy equivalent to a for mal charge of +6. The nitrogen 1s binding energies varied in a systema tic manner that reflected the change in oxidation state. The XPS resul ts have been used to provide insight into the formation of these compo unds in two reaction systems.
